Sounds like maybe you have generated an avatar definition for your new model / rig, that's usually the case when no anims are applied, I'd take a look at the avatar definition in the Rig tab of your blender import to make sure one is generated and that it's assigned in your animator

could you go further in depth on what this means, I have very little awareness of how 3D modelling and riggin works and do not know what you are telling me to do here ?

when i open my rig in the inspector this is all I see

oh i think i see what you meant now

it seems like I didn't make a new avatar but my player animator is linked to the old avatar from before i switched

so how do I make a new animator?
